Hi,

during page event I got this error.

I found another similar issue
https://www.outsystems.com/forums/discussion/21644/how-to-fix-invalid-invalid-column-name-after-adding-a-column-in-the-table/

gave the some solution

1.Change the name

2. Set the column to not required. [yes. the column is not required]

3. Try to add another column and see if it works 

4. Try to Republish again 

5. Check Database itself [DB has the column ard]

    > The columns weren't created. This is a bit weird as attribute has been added in the Entity

6. Refreshed all dependencies. [no refers issue]

7. Check Service Center Error Log every time you do fixes

any other advise about it? outsystems version 10.0.906.0
